Hi,

I just installed the Flowmaster Force II cat-back kit with their 50-series SUV/Performance muffler.

I now have the ~2100 RPM drone at 70-80 MPH.

This is a 2K2 'Gator w/ the 5.4L motor.

I don't really want to tear out the system and try to return it. It came from Jegs.

So what now? I'd imagine a new muffler will take care of this. But which one? Is there one that has the approximate size as the Flowmaster 50? Which one would be best for my application?

Thanks,
JAMES.

 

How about a 70 series flowmaster? Its not as loud as the 50 but you still get the performance upgrade. Here's the link:
